Hypersegmented neutrophils and reversible hyperpigmentation in vitamin B(12) deficiency in Ghana.
Article in BMJ case reports, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The present report concerns three cases of vitamin B(12) deficiency in Ghana. One case presented in the expected textbook manner with neurological signs, anaemia and a low serum vitamin B(12) level, whereas another presented with anaemia and hyperpigmentation, but a high serum vitamin B(12) level. Both responded well to treatment with vitamin B(12). It is suggested from the literature that the high serum vitamin B(12) may have been the result of high intrinsic factor antibodies. The third patient presented with haemolytic anaemia with depression, and was managed as such initially. She responded well, with a normalisation of haemoglobin levels. Persisting vague neurological symptoms lead to a check of serum vitamin B(12), which was found to be low. Her symptoms cleared with vitamin B(12) treatment. The need for a pragmatic approach in diagnosing vitamin B(12) deficiency is stressed.
